Abstract

To increase power density in gas-discharge lasers based on combined DC-CPD discharge technology (DC + Capacitively-coupled Periodic-pulsed Discharge) one have to increase pulse current density of CPD. Thus electrical and chemical processes in CPD were studied in pulse current density limits expanded up to 500 mA/cm². It was shown that CO₂ dissociation rate is increased with current density and pulse repetition rate and is different in near-electrode sheath and in the discharge gap. Catalytic stabilization method of the gas mixture composition is proposed for CPD at higher pulse current densities.
